Need some help with a 2 speed axle
Just picked up a 68 C60 grain truck, 350, 4spd, 2spd rear, having trouble getting the rear to shift, have power all the way into the shift motor on both wires ( depending on switch position), but she doesnt do a thing. I'm thinking i'm missing a ground wire on the rear end somewhere, or did they ground through the rear end/frame somehow? Hoping someone with some 2 spd knowledge will chime in. BTW its is the 2 wire motor, not the newer style 3 wire.

Re: Need some help with a 2 speed axle
If I remember my bus right, it grounds through the rear end. However, the limit switch was shot when I bought it, so I could only shift into LO. I could shift into HI if I reversed the wires. Obviously that would only work while parked with the shifter assembly removed & grounded directly to the battery.
I found a limit switch in a salvage yard V60, and the bus shifted fine after that. Can you shift it at all if you reverse the wires?

Re: Need some help with a 2 speed axle
How about the switch inside the shifter mechanism on the rear end? That's the one that was shot on my bus.
